The present invention provides a kind of wollastonite fibre plastic matrix and preparation methods.By wollastonite fibre after high-temperature calcination and surfactant pretreatment, it is scattered in acetone, ball milling is carried out after carboxymethyl chitosan mixing is added, polyvinyl butyral is added after taking-up, continue ball milling, modified silicon ash mineral wool is obtained, is mixed with matrix resin and extruding pelletization is to get wollastonite fibre plastic matrix.This method by carboxymethyl chitosan by being adsorbed in wollastonite fibre surface, improve the dispersibility and stability of wollastonite fibre in the plastic, polyvinyl butyral is adsorbed in wollastonite fibre surface simultaneously, improve the compatibility of storeroom, when gained plastic matrix is filled into polymeric matrix, it can be obviously improved the intensity, rigidity and dimensional stability of material, can be widely used for reinforced plastics field. |
